DOOM Retro v2.7 is now available. It may be downloaded here, and its release notes are as follows:

With John Romero’s express permission, E1M4B: Phobos Mission Control and E1M8B: Tech Gone Bad are now included with DOOM Retro. If either the DOOM Registered or The Ultimate DOOM IWADs are loaded, these maps may be played by entering map E1M4B or map E1M8B in the console.

DOOM Retro’s splash screen has been redesigned.

Extensive optimizations have been made to further improve the overall performance and stability of DOOM Retro.

The format of savegames has changed, breaking compatibility with previous versions of DOOM Retro.

Minor changes have been made to text that is output to the console.

Further improvements have been made to the console’s autocomplete feature.

The player can now jump once the new +jump action has been bound to a control using the bind CCMD.

Improvements have been made to BOOM-compatible translucent wall textures when the r_dither CVAR is on.

Further improvements have been made to the support of DEHACKED and MAPINFO lumps.

The console’s background has been given a slightly green tint and can now also be changed using the new con_backcolor CVAR. It is 12 by default.

The player is now also given all power-ups when entering give all in the console.

A bug has been fixed whereby entering give cellpack in the console would give the player a box of bullets instead.
